GENPLT-II\\ IS A PACKAGE OF ^^FORTRAN\\ NON-INTERACTIVE GRAPHIC
SUBROUTINES WHICH PROVIDE A WIDE VARIETY OF AUTOMATIC FUNCTIONS SUCH
AS THE PLOTTING OF SCALES AND GRIDS.
^DATA CAN BE REPRESENTED BY PLOTTED POINTS OR SYMBOLS,
BY SOLID OR DASHED LINES, OR AS SHADED FIGURES.
^DRAFTSMAN'S ^GOTHIC AND ^GREEK LETTERING ARE PROVIDED.

^FURTHER INFORMATION CONCERNING THESE ROUTINES HAS
BEEN PUBLISHED IN ^VOLUME 3 OF "^COMPUTER ^PROGRAMS

.SKIP 2
^THE ^^GENPLT-II\\ SUBROUTINES PRODUCE GRAPHIC OUTPUT ON A
SPECIFIC PLOTTING DEVICE BY CALLING A SET OF ROUTINES PROVIDED
BY THE USER FOR THAT DEVICE.
^SEVERAL TYPICAL PACKAGES OF SUCH COUPLING ROUTINES
ARE SUPPLIED.
^IF AN INSTALLATION HAS A PLOTTING DEVICE, SOME PRIMITIVE ROUTINES
WILL PROBABLY BE AVAILABLE FOR ITS USE.
^ONE OF THE PROVIDED COUPLING PACKAGES CAN THEN BE MODIFIED
TO CALL THESE PRIMITIVE ROUTINES.
^THE FILE ^^PENTST\\ IS PROVIDED TO TEST A NEW OR MODIFIED
SET OF COUPLING ROUTINES.
^IF THE COUPLING ROUTINES ARE OPERATING CORRECTLY, THIS
PROGRAM WILL PRODUCE 3 VERSIONS OF THE ^YALE ^UNIVERSITY
CREST.
.SKIP
^EACH OF THE COUPLING PACKAGES CONTAINS 5 SIMPLE ROUTINES WITH
A STANDARDIZED ARGUMENT LIST. ^THESE ARE AS FOLLOW.
.SKIP
.LEFT MARGIN 4
^^SUBROUTINE PENBGN(LASTX,LASTY,NEWX,NEWY)

\\CALLED BY THE USER TO INITIALIZE ANY PARAMETERS NEEDED
BY THE OTHER ROUTINES OF THE COUPLING PACKAGE.
^THE MOST IMPORTANT PARAMETERS ARE ^^FACTOR\\ WHICH IS THE NUMBER
OF PLOTTER GRID UNITS CORRESPONDING
TO ^^XWIDTH\\ OR ^^YWIDTH\\ EQUAL 1.0 (THE MAXIMUM POSSIBLE),
AND ^^OFSETX\\ AND ^^OFSETY\\ WHICH ARE THE COORDINATES
OF THE PLOTTER GRID ORIGIN STATED IN PLOTTER GRID UNITS.
^^PENBGN\\ MIGHT ALSO
PRODUCE AN IDENTIFICATION FRAME IF USED WITH A CAMERA MONITORED ^^CRT\\,
OR MIGHT ADVANCE PAPER IF USED WITH A DRUM PLOTTER.
.SKIP
^^SUBROUTINE PENHLT(LASTX,LASTY,NEWX,NEWY)
.BREAK
\\CALLED BY THE USER WHEN A FRESH PLOTTING
SURFACE MUST BE PROVIDED. ^WOULD ADVANCE FILM IN
^^CRT\\ CAMERA OR ADVANCE THE PAPER IN DRUM PLOTTER. ^FOR A
FLAT-BED PLOTTER, WOULD SIGNAL THE OPERATOR TO CHANGE
PAPER. ^FOR A STORAGE ^^CRT\\, WOULD CLEAR SCREEN.
.SKIP
^^SUBROUTINE PENEND(LASTX,LASTY,NEWX,NEWY)

^THE STYLUS OF THE TELECOPIER SPINS INSIDE A
ROLLED SHEET OF CARBON PAPER WHICH
IN TURN IS INSIDE A ROLLED SHEET OF NORMAL PAPER.
^THE OTHER PRINTER COUPLING ROUTINES CAN BE USED
SINCE BOTH THE PRINTER AND TELECOPIER ARE RASTER DISPLAYS.

^SINCE THE ^^GENPLT-II\\ FONTS WERE
ORIGINALLY DEVELOPED FOR USE ON AN ^^IBM\\ 7094 COMPUTER, ONLY
THE CHARACTERS IN THE ^^BCD\\ CHARACTER SET CAN
BE USED IN INPUT STRINGS.
^THESE ALLOWED CHARACTERS INCLUDE THE UPPER CASE ^ROMAN ALPHABET,
THE NUMERALS 0 THROUGH 9, AND THE 11 OTHER CHARACTERS
LEFT PARENTHESIS, RIGHT PARENTHESIS, COMMA, APOSTROPHE,
PERIOD, PLUS SIGN, MINUS SIGN, ASTERISK, SLASH, EQUALS SIGN
AND DOLLAR SIGN (USED AS A NON-PLOTTING CONTROL CHARACTER).
^ALL OTHER CHARACTERS WILL BE TRANSLATED TO BLANKS (SPACES)
PRIOR TO BEING PLOTTED.
.SKIP
^THE BASIC VERSION OF THE LETTERING ROUTINE (^^FONT1C\\)
PLOTS ONLY HORIZONTAL OR VERTICAL UPPER CASE ^ROMAN BLOCK LETTERS. ^PLOTTING OF
THE STRING IS TERMINATED WHENEVER A $ (DOLLAR SIGN, NOT
ALT-MODE) IS ENCOUNTERED AS A CHARACTER TO BE PLOTTED.
^THE CAPTION
.NOFILL
^^ THIS IS A SAMPLE TITLE\\
.FILL
COULD BE PLOTTED IF THE FOLLOWING ^HOLLERITH FIELD WERE
TO BE INCLUDED AS ONE OF THE CAPTION ARGUMENTS (SUCH AS
^^NAMELX, NAMELY\\ ETC.#OF A ^^CALL SCLPLT\\ STATEMENT).
.NOFILL
^^ 23HTHIS IS A SAMPLE TITLE$\\
.FILL
^IT WILL BE NOTED THAT THE $ MUST BE INCLUDED IN THE
CHARACTER COUNT AND THAT THIS CHARACTER COUNT CAN BE
LESS THAN THE 72 MAXIMUM. ^IN EFFECT, THE TERMINAL $
PREVENTS THE PLOTTING AS RANDOM CHARACTERS OF THE
UNSPECIFIED PORTION OF THE CAPTION.
.SKIP
^THE ADVANCED VERSION OF THE LETTERING ROUTINE (^^LTRPLC\\)
CAN PLOT LETTERING AT ANY ANGLE, AND
INTERPRETS THE CHARACTER FOLLOWING A $ IN A PLOTTED
ALPHAMERIC STRING AS AN OPTION SELECTOR RATHER THAN AS
A CHARACTER TO BE PLOTTED. ^A BLANK (SPACE CHARACTER), ZERO OR ANY OTHER
CHARACTER NOT USED FOR PARTICULAR OPTIONS FOLLOWING A
$ CAUSES TERMINATION OF PLOTTING OF THE STRING. ^THE
DIGITS 1, 2, 3 AND 4 SELECT ^ROMAN UPPER CASE, ^ROMAN
LOWER CASE, ^GREEK UPPER CASE AND ^GREEK LOWER CASE
RESPECTIVELY (IN FONTS 7 AND 8, SEMI-SCRIPT ^ROMAN
IS SELECTED RATHER THAN ^GREEK BY $3 AND $4). ^ROMAN
UPPER CASE LETTERING IS INITIALLY PROVIDED, HOWEVER THIS
ALPHABET AND CASE ARE NOT AUTOMATICALLY RESET BY SUCCEEDING CALLS TO
THE LETTERING PROGRAM. ^THE SAMPLE CAPTION GIVEN ABOVE
COULD BE PLOTTED WITH THE FIRST LETTER IN EACH WORD IN
UPPER CASE BY USING THE FOLLOWING STRING.
.NOFILL
^^ 40H$1T$2HIS $1I$2S $1A S$2AMPLE $1T$2ITLE$ \\
.FILL
^GREEK LETTERS ARE IDENTIFIED IN THE CHARACTER
STRINGS BY THE ^ROMAN LETTERS HAVING THE SAME NUMERICAL
POSITIONS WITHIN THE CORRESPONDING ALPHABETS. ^FOR
EXAMPLE, $3^X WOULD REFER TO UPPER CASE OMEGA, THE 24TH
CHARACTER IN THE ^GREEK ALPHABET.
.SKIP
^ITALIC LETTERING, SIZE MODIFICATION, AND SUB-SUPERSCRIPTING
ARE PROVIDED BY THE FOLLOWING OPTION SELECTOR CHARACTER
PAIRS.
.NOFILL
$$ SELECTS ITALIC LETTERING.
$* SELECTS LETTERING AND INTERCHARACTER SPACING BOTH OF
3/2 NORMAL SIZE.
$/ SELECTS LETTERING AND INTERCHARACTER SPACING BOTH OF
2/3 NORMAL SIZE.
$+ SELECTS SUPERSCRIPT LETTERING.
$- SELECTS SUBSCRIPT LETTERING.
$) SELECTS LETTERING 3/2 NORMAL WIDTH.
$( SELECTS LETTERING 2/3 NORMAL WIDTH.
$= CAUSES RETURN TO NORMAL UPPER CASE ^ROMAN.
.FILL
^THESE OPTIONS ARE CUMULATIVE UNTIL THE ENTIRE GROUP IS
RESET BY TERMINATION OF PLOTTING OF THE STRING OR BY THE
$= OPTION SELECTOR PAIR. ^IF ITALIC SUPERSCRIPTING HAD
BEEN REQUESTED BY A $$$+ OR $+$$ SELECTOR SET, ITALIC
SUBSCRIPTING COULD BE SIMPLY OBTAINED BY USE OF THE $-
SELECTOR PAIR (THOUGH A REDUNDANT $$ WOULD CAUSE NO HARM).
^HOWEVER TO OBTAIN NORMAL SIZE ITALIC LETTERING UNDER
THE SAME INITIAL CONDITIONS, IT WOULD BE NECESSARY
TO USE A $=$$ OPTION SELECTOR SET, SINCE THE $= OPTION
SELECTOR PAIR WOULD REMOVE THE ITALIC SLANT AS WELL AS
CAUSE RETURN TO THE NORMAL LETTERING SIZE.
.SKIP
^A COMMA FOLLOWING A DOLLAR SIGN CAN BE USED TO BACKSPACE.
^SUCH A BACKSPACE HAS THE SAME WIDTH AS HAVE MOST OF THE UPPER CASE
^ROMAN LETTERS AND AS HAVE ALL THE DIGITS AND PUNCTUATION MARKS AND
UPPER AND LOWER CASE ^GREEK LETTERS.
^A PERIOD FOLLOWING A DOLLAR SIGN CAN BE USED TO SHIFT
THE PLOTTED OUTPUT TO A NEW LINE, SIMILAR TO
INCREMENTING THE ^^LINE\\ ARGUMENT OF ROUTINE ^^WRDPLT\\.
^THE NEW LINE COMMAND SHOULD ONLY BE USED, HOWEVER, IF
THE LETTERING IS BEING LEFT JUSTIFIED.
